If you are a chemistry major, you might want to take him. However, if not, you should steer clear. His tests are progressively cumulative, overly complex, and time consuming ? making it easy to bomb if you aren?t having a good day. A major flaw in his teaching style comes from his insistence on memorizing large volumes of irrelevant data.

Yes, it's tough and hard but you'll finish this class as an expert in ochem. He says a lot of stuff like you have to read ahead of class and you have to ochem everyday. I disagree. Also, so much extra credit

Professor Blackstock was an amazing professor. He expects a lot from you, and you must work really hard to do well. Although I enjoyed having Shaugnessy for 231, Blackstock gives you more opportunities to raise your overall grade. He made me genuinely enjoy organic chemistry, which is something I was definitely not expecting to happen!

Prof Blackstock is normally an O-chem teacher, making his chem 101 lectures a lot more complex than they really should be. He expects you to do A LOT of outside work on your own (e.g. reading before/after lecture). His lectures don't do much, but daily attendance is taken.

Dr. Blackstock is my favorite organic chemistry professor! I struggled a lot with organic I and was very worried about my performance in organic II. However, after putting in lots of work and going to his office hours every week, I managed to do very well in the class. The practice exams and homework are very helpful and will help you excel.

Organic is a lot of content no matter who you take. His tests could have been a lot tougher given the content covered. Do the practice tests and recomm hw problems and go to his office hours!! HW and bonus quizzes can add 5% to final grade. Passionate man and if you participate in class he will appreciate you, but he won't tolerate complaining

Organic Chemistry is a difficult course, but Dr. Blackstock helps to make it much easier. He provides practice exams before each midterm and offers up to 20 points extra credit for doing simple assignments throughout the semester. Exams are worth 600/645 points in the class, so it can be hard to recover from one poor exam. Great choice for CH231.

While Dr. Blackstock is a very intelligent man, he was by far the worst professor I have had at UA. I found him impossible to reach and unwilling to help at all outside of the classroom. If the material does not automatically click, you will spend HOURS teaching yourself outside the class. Biggest time commitment I have ever had for a single class.

He's very passionate about Chemistry and does a decent job as a teacher, however his class is painfully difficult and hard for no reason. About 80% of the class grade is tests, each having about 60% free response. The amount of material covered is absurd to the point where studying for 40hrs on just one test only nets a low B. Avoid AT ALL COSTS

Dr. Blackstock is a very intelligent man who knows a lot about his field and is very passionate about it. That said, I did not like him as a professor. He expected students to fully know and understand even the smallest things he mentioned in class. Not to mention how about 90% of your grade is JUST exams(which were pretty difficult).

He's accessible and offers abundant resources for students. Although the total grade is test heavy, homework and quizzes are bonus along with bonus on each test. His lecture notes are more helpful than any teacher that reads word for word off slides so that class is not dreadful. I read the book and did the homework, and I did well.

Dr. Blackstock is a knowledgeable professor, but wow, this class was hard. He expects you to know every little detail, so it's really time-consuming. If you put in the work, you'll do well, but I wouldn't take another hard class with it. I did learn a ton, but he acts as if it's the only class his students are taking which made it very stressful.

This class is a weed-out class. I didn't do half the homework and got Bs on two of my exams, but when I started paying attention in class, I was able to bring my grade back up to an A. If you aren't a good test taker, this class will be your demise. If you are, you probably only need to put 5ish hours of studying for each exam.

READ THE TEXTBOOK BEFORE CLASS! He teaches this class well, but YOU have to put in more work than just showing up to lecture every week. Orgo II is a very dense class & there's no way around that. Some of his T/F questions are diabolical, but other than that he doesn't try to trick you (too much) on exams.

It's a LOT tougher than orgo 1 hands down. Read the textbook, come to class...he's honestly not that bad although there are some crazy T/F and structure-drawing q's. If you treat this as your toughest class, an A is completely possible with a good 20-25hrs prep before tests. If you can't get >70s on these tests you need to srsly rethink premed.

I'm not the best at chem in general, but this is by far the hardest class i've ever taken. For orgo 2, be ready to over prepare for test 1 and 2, it will set you up well for the next tests. he does not post video lectures, so be prepared to go to every class. He gives a good amount of extra credit, and he is quite good at getting info across.

His class was not quite as bad as I expected it to be, but it was hard. He is super passionate about what he teaches, and this leads to some unnecessarily high expectations, which is compounded by the fact that the class is based almost entirely on test grades. Test 2 is tough, so I would plan to drop that one and replace it with the final.

If you do not have a good foundation from orgo 1 (which I took with a different prof), his class will be exceedingly difficult. He lectures EXTREMELY fast, you need to learn basically everything on your own ahead of time. The recitations are just more lecturing. If you want a true review from him, you need to attend office hours.

Orgo is a hard class no matter what but Dr.Blackstock's tests are very difficult and require mastery level of material. He provides you with a ton of resources and hosts group office hours which are helpful, but I struggled with the pace and amount of material. The homeworks after unit 2 take on average 7 hours. Youtube is your bff for this class.

The class is very difficult, and exams make up 93% of your grade. His love for chemistry is contagious and he's great at explaining content. Tests are hard but graded in a way that rewards an in depth understanding of content. I recommend taking him for Organic 1 because he's the only professor for Organic 2. Advantageous to understand his style.

Blackstock would rush through every topic in class. A couple of problems that were given on his exams were topics that I'm pretty sure he did not cover in class. You basically have to teach it all to yourself.

Blackstock is one of the nicest and most understanding professors I've ever had BUT this class is very difficult and I felt as though the time I put in did not pay off. His exams are very hard, and worth the majority of your grade. I have heard the final is easier so we will see.

Memorize EVERYTHING. He gives partial credit, which is nice. Lectures are super important and helpful. Frustrating because the last 2 units are rushed. He will ask you to draw a random compound he pointed out once, so be prepared. Overall, though, he is very sweet, and you can tell how much he loves the subject. I fear and respect him.

This class is just hard. Dr. Blackstock is so nice though. His tests can be tricky and he will sometimes ask specific questions about things we breezed over in class. He fully expects you to read the textbook also. You have to put in a ton of work to do well, but Dr. Blackstock is 100% willing to help you. He build bonus into the tests also.

Orgo is excruciatingly difficult. Most poor opinions reflect the class difficulty rather than the professor. Prof is decent (encouraging, loves chemistry, very accessible) but is not good at explaining. Must read the textbook. Tutoring is your best friend. Expect to spend minimum an hour every day outside of class on orgo.

Extremely difficult class. Homework takes very long to do and he 100% expects you to read the textbook. Hard sometimes to balance other classes with this one since it takes up such a majority of your time. Offers partial credit on tests and sometimes asks you very specific things he mentioned once in class. Does offer extra credit which is nice

Blackstock's class was the closest I've come to making a B in my life. Tests are worth 93% of the grade, and the other 7% is given with attendance questions which are tricky. He breezes over concepts and likes to implement the smallest of topics covered in class on his midterms. The final can be worth up to 50% of grade and is easier (It saved me)

Overall, he is a tough professor but the class is doable. You need to read the chapter and do all the problems he recommends and then some, which simply requires time and dedication. His multiple choice can be really tricky, so if there is anything you have questions about absolutely ask. The final is way easier, but still heavy studying all around

Blackstock is a nice guy but bad at explaining things. Assigns ridiculous amounts of HW, but it's important you do it for practice. He will test you on topics not taught in class or in the textbook, but because it is a concept you need to reason, it's fair game. The attendance questions are hard, so you will not get full credit if you are wrong.

This class was hard, but not as bad as everyone else makes it seem. I never read the textbook, just made sure i knew all the lecture material and was fine. Blackstock is a nice guy just makes his tests really hard, but they are doable. The final is easy and replaces your lowest test which helps. I would choose another professor if it's an option.
